20.500.12556/RUL-110503 Izvedba in analiza merilnega sistema za pretok plina z laminarnim merilnikom Realization and analysis of the measuring systems with a laminar flow element V laminarnem tokovnem elementu določamo pretok plina, katerega snovske in transportne lastnosti poznamo, na podlagi merjenja tlačne razlike med vstopom in izstopom iz elementa, absolutnega tlaka in temperature plina. V zaključni nalogi smo postavili merilni sistem z laminarnim tokovnim elementom in v programskem okolju LabVIEW izdelali nadzorni program. Merilni sistem smo uporabili za meritve pretoka suhega zraka, za katere smo ocenili smo tudi merilno negotovost. Ustreznost dobljenih rezultatov smo preverili s primerjavo z izmerki referenčnega merilnega sistema. In a laminar flow element the gas flow rate, which physical and transport properties are known, is based on measured pressure difference between the inlet and the outlet of the element, the absolute pressure and the temperature of the gas. In this diploma thesis, we set up a measuring system and created a control program using LabVIEW programming environment. The measuring system was used to measure the flow rates of dry air, for which we also evaluated the measurement uncertainty. The comparative measurements with the reference measuring system were used to analyse the obtained results. laminarni elementi Hagen-Poiseuillov zakon merilna zmogljivost En število nadzorni programi laminar flow elements Hagen-Poiseuille law measurement capability En number control programs true false false [K.
